- A
Compute Savings Plans
Compute Savings Plans apply to EC2, Lambda, and Fargate usage and provide flexibility across instance families, regions, and operating systems. They are the correct choice for the team's requirements.
- B
EC2 Instance Savings Plans
Why wrong: EC2 Instance Savings Plans provide a lower discount than Compute Savings Plans but are restricted to a specific instance family within a region. They do not cover Lambda usage, so this does not meet the team's needs.
- C
Reserved Instances
Why wrong: Reserved Instances (standard or convertible) are tied to a specific instance type, region, and tenancy. They do not offer the cross-family or cross-region flexibility the team requires, and they do not cover Lambda usage.
- D
Spot Instances
Why wrong: Spot Instances offer steep discounts but are based on spare EC2 capacity and can be interrupted. They do not involve a long-term commitment or guarantee cost savings across a consistent usage baseline.
CLF-C02 Billing, Pricing, and Support Practice Question
This CLF-C02 practice question tests your understanding of billing, pricing, and support. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company runs a combination of Amazon EC2 instances and AWS Lambda functions for its applications. The finance team wants to reduce costs by making a commitment to a consistent amount of compute usage (measured in dollars per hour) for a 1-year term. The team wants the flexibility to change instance families, sizes, and AWS regions, and also wants the commitment to cover both EC2 and Lambda usage. Which AWS pricing option should the team purchase?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Compute Savings Plans
Compute Savings Plans provide the required flexibility to change instance families, sizes, and AWS regions, and they automatically apply to both EC2 and Lambda usage. This plan offers a discounted hourly rate in exchange for a 1-year commitment to a consistent amount of compute spend (measured in dollars per hour), making it the only option that meets all the stated requirements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Spot Instances offer steep discounts but are based on spare EC2 capacity and can be interrupted. They do not involve a long-term commitment or guarantee cost savings across a consistent usage baseline.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Compute Savings Plans with EC2 Instance Savings Plans, mistakenly thinking the latter offers the same flexibility, but EC2 Instance Savings Plans are restricted to a single instance family and do not cover Lambda or Fargate.
Detailed technical explanation
How to think about this question
Compute Savings Plans apply to any EC2 instance usage (including different families, sizes, and regions) and also to AWS Lambda and AWS Fargate usage, automatically applying the lowest available price. The commitment is measured in dollars per hour (e.g., $10/hour), and any usage beyond the commitment is charged at standard on-demand rates, ensuring cost predictability without sacrificing flexibility. This model is ideal for workloads with variable compute needs across multiple services.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
